IP Address Checker

Find your public IP, geolocate any IP and get ISP, ASN, timezone and VPN/proxy detection.

Your public IP address as seen by the Internet.

Examples: 8.8.8.8 1.1.1.1 208.67.222.222 2001:4860:4860::8888
192.168.1.1 10.0.0.1 172.16.0.1 192.168.0.0/24 10.0.0.0/8 255.255.255.0

What is an IP address checker used for?

An IP address checker lets you know your public IP address — the unique identifier assigned by your Internet Service Provider (ISP) — and get associated geolocation information: country, city, GPS coordinates, timezone and network operator. It's useful for diagnosing connection issues, verifying a VPN is working correctly, or analyzing a suspicious IP.

IPv4 vs IPv6

An IPv4 address consists of 4 octets separated by dots (e.g. 192.168.1.1). There are about 4.3 billion IPv4 addresses. An IPv6 address uses 8 groups of 4 hexadecimal digits (e.g. 2001:0db8::1) and provides 3.4×10³⁸ addresses. IPv6 deployment is accelerating as public IPv4 addresses have been exhausted since 2019.

How to detect a VPN or proxy?

A VPN or proxy changes your visible IP address. Detection indicators include: the ASN belonging to a hosting provider or datacenter (OVH, AWS, DigitalOcean) rather than a residential ISP, a mismatch between the browser timezone and the IP timezone, or presence in known blacklists. Our tool analyzes these signals to identify suspicious connections.

Frequently asked questions

A private IP address is used within your local network (LAN): 192.168.x.x, 10.x.x.x or 172.16.x.x to 172.31.x.x. It is not accessible from the Internet. A publi... A private IP address is used within your local network (LAN): 192.168.x.x, 10.x.x.x or 172.16.x.x to 172.31.x.x. It is not accessible from the Internet. A public IP address is assigned by your ISP and identifies your connection on the Internet. Multiple devices on your network share the same public IP through NAT (Network Address Translation).

Most ISPs assign dynamic IP addresses that change periodically (at each router restart, after 24h, or per contract). A static IP stays the same permanently and ... Most ISPs assign dynamic IP addresses that change periodically (at each router restart, after 24h, or per contract). A static IP stays the same permanently and is usually obtained as a paid option. On mobile, the IP changes with each reconnection to the cellular network. A VPN changes the IP visible from the Internet while keeping your local private IP.

The tool detects several signals associated with VPNs and proxies: ASN belonging to a hosting provider or datacenter (OVH, Hetzner, AWS, DigitalOcean) rather than a residential ISP (AT&T, Comcast, BT), the proxy flag returned by the ip-api.com API, and the hosting flag for known hosting provider addresses. Detection is not foolproof — some VPNs use residential IP blocks to bypass this type of detection.

The ASN (Autonomous System Number) is a unique numerical identifier assigned to an internet network managed by a single organization (ISP, company, university).... The ASN (Autonomous System Number) is a unique numerical identifier assigned to an internet network managed by a single organization (ISP, company, university). For example, AS15169 belongs to Google, AS3215 to Orange France, AS16509 to Amazon AWS. The ASN identifies who controls the IP address block to which an address belongs, allowing you to distinguish a residential ISP from a cloud hosting provider.

IP geolocation is accurate at the country level in ~99% of cases, at the region level in ~80% of cases, and at the city level in ~50-70% of cases. The GPS precision shown is indicative — it's the center of the estimated city or area, not your exact address. Dynamically assigned IP addresses may point to the ISP's datacenter rather than your actual location.
